Marvel Super Heroes: War of the Gems

Sent in by Mark Genro
After you defeat Thanos, all of the gems fly in the air, spin
around, and they all meld together to become one big gem. Adam
Warlock takes it, saying that it will never fall into the hands of
evil again. All the heroes go back to earth. The game shows a
picture of earth as it says END.
